VISE.

SPECIFICATION forming part of Letters Patent No. 417,982, dated December24, 1889.

Application iiled J'ulyr 19, 1889.

To @ZZ whom zit may concern/ Be it known that I, GEORGE S. BUCK, ofSisseton Agency, in the county of Roberts and Territory of Dakota, haveinvented certain new and useful Improvements in Vises; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to an improvement in vises; and it consists in thecombination of two jaws, an operating screwthreaded rod, which passesthrough the jaws, and a nut secured to a board inside of two strips, asupporting-frame, which is secured to the board, and a support, which issuspended from the screw-rod and connected to the outer jaw at its lowerend, as will be more fully described hereinafter.

The objects of my invention are to make the vise and all of itsattachments vertically adjustable to support the outer jaw both at itsupper and lower end, so that it moves horizontally, and to make theouter jaw vertically adjustable, so as to compensate for wear of thejoints andV bearings.

Figure l is a side elevation of a vise which Fig. 2 is a front view ofthe same. Fig. 3 is a plan view.

A represents the outer Ajaw of the vise, and B the inner one. Secured tothe outer side of the work-bench are the two strips C, of any suitablewidth, and which are separated from each other a suitable distance, soas to allow the screw-rod D and the support F of the lower end of theouter jaw A to be adjusted up and down freely between them.- Placed in,direct contact with these strips C on their inner sides is the board G,of suitable width, and to which the inner jaw B is rigidly clamped bybolts or screws, which pass through the slots Hin the lower portion ofthe strips C, as shown. The board G is not connected to the strips C,but is held in direct contact therewith both by the screwrod D and bythe bolts or screws which pass through its lower end into the inner jawB. The jaws A B and the board G can be freely Serial No. 318,016. (Nomodel.)

adjusted vertically in relation to the strips O and to the work-bench,according to the nature of the work that is to be performed, and thevise is supported by the pivoted catch I upon one side of the inner jawB, and which engages with a notched plate J, secured to one of thestrips O by the side of the jaw B, as shown.

Secured to the upper end of the board G is a nut L, through which thescrew-rod D* passes, and this rod` has its smooth inner end to project asuitable distance beyond the screwthreaded portion. The outer jaw A canonly be moved the length of the screw-threaded portion; but the wholerod moves endwise as the jaw is opened and closed. In order to supportthe inner end oi' this rod D, suitable triangular frames or bearings Nare secured to the upper and lower ends of the board G, and these twoframes N are connected together by a box or bearing O, through whichtherod D passes. This box serves both to brace the frames N together and asa support for the inner end of the rod, so as to prevent it from saggingdown from the weight of the jaw A, which is secured at its lower end tothe lower end of the support F. The upper end ofthe support F isbifurcated or pronged, as shown, and these twoprongs are held betweenthe screw-threaded portionl of the rod and nut P on its outer end. Thelower end of the support F passes through an opening in the lower end ofthe board G and through a similar opening in the lower end of the innerjaw B, and is clamped to the lower slotted end of the jaw A, as shown.The slot Q in the lower end of the jaw A al lows the jaw to be adjustedvertically upon the support F, so as to compensate for the wear ofjoints and bearings, dac. As the lower end of the jaw A is secured tothis rigid support F, which is carried-back and forth by the screwr0d D,the entire jaw moves horizontally, and thus is adapted to be used inconnection with the finest or coarsest work.

Having thus described my invention, I claim- The combination of the twojaws A B, the screw-rod which passes horizontally through them, theboard G, a nut secured to the board IOO and through which the screwpassos,two bent In testimony'whereof I ax my signature rods N, secured'uo-the board G and connected in presence of two Witnesses. together bya box or bearing O, and a rigid K support F, Which slides freely backand forth GEORGE S.
